Comet Tsuchinshan-ATLAS (C/2023 A3) will likely remain visible to the naked eye through October 21st and the largest supermoon of the year will rise on Thursday.

A rare comet was spotted streaking across the Colorado sky the past two nights, with sightings anywhere from Highlands Ranch to South Park.

Just days after the northern lights painted the sky in a vibrant array of colors as far south as Ouray, a potentially once-in-a-lifetime comet has dazzled Coloradans this week.
